Gas vs electric running cost calculator

Put in your yearly gas use and prices, tick what runs on gas, and see roughly what each appliance would cost to run on electricity instead. Most households find heating is where the money is, and that the full saving only arrives once the gas account is closed.

Your gas use Gas used per year (MJ)Add up the MJ on your last four bills. Only have one? A winter bill is often about 40% of the year, a summer bill about 10%.

Cooking takes whatever is left. Typical Melbourne split with gas ducted heating: about two-thirds heating, a quarter hot water, the rest cooking.

Electricity Electricity usage rate (c/kWh) Share of hot water heated from your own solar (%)0 if you don't have solar. 50 to 70% is realistic with a daytime timer. Solar feed-in tariff (c/kWh)What you give up by using the solar instead of exporting it.

Assumes a gas heater at 75% seasonal efficiency vs reverse-cycle at an average COP of 3.5; gas hot water at 65% (storage losses included) vs a heat pump at COP 3.3; gas cooking at about 40% vs induction at about 85%. Real results vary with the house, the equipment and how you use it.
